This technique was mentioned by Konan after her fight with Tobi. Seeing her paper flower falling apart, she remarks that her Paper Ocean Technique required more chakra than she thought.

Trivia

The Japanese word for paper person (紙者, shisha) is pronounced the same as the Japanese word for messenger (使者, shisha). This gives the name of this technique the additional meaning Messenger of God — a messenger of God being an angel, which is also Konan's moniker.
